Resource Type:: Technical Report

Creator:: Viguers, Leslie and Fisher, J. R.
Abstract:: The wine grape industry is rapidly growing in Oregon. By the year 2005, we could predict that Oregon will have over 10,000 acres in wine grape production. At a meeting last year, the Grapevine Improvement Committee acknowledged that little was known about the presence of potential pest and beneficial insects...

Creator:: Ingham, Russell E., Forge, Thomas, Strik, Bernadine C., and Pinkerton, J. N.
Abstract:: Objectives 1. Survey Oregon vineyards for the presence, identity and abundance of plant-parasitic nematodes. 2. Relate the distribution and abundance of potentially pathogenic species to viticultural practices and site characteristics. 3. Evaluate the efficacy of Nemacur for reducing populations of plant-parasitic nematodes. 4. Document seasonal changes in the abundance of...

Creator:: Pinkerton, Jack, Candolfi-Vasconcelos, M. Carmo, and Ingham, Russell
Abstract:: Survey data compiled in 1995 showed that plant-pathogenic nematodes that cause yield loss in California and European vineyards are found in over 85% of Oregon vineyards. In over 37% of the samples collected, population densities of Xiphinema wnericanwn (dagger nematode) and Criconenw1la xenoplax (ring nematode) were greater than levels known...

Creator:: Ingham, Russell E., Strik, Bernadine C., Forge, Thomas, and Connelly, Ann
Abstract:: Objectives: 1. Survey Oregon vineyards for the presence, identity and abundance of plant parasitic nematodes. 2. Document seasonal changes in abundance of species of important plant parasites in order to identify optimum times for sampling. 3. Evaluate the efficacy of Nemacur for reducing populations of plant parasitic nematodes.

Creator:: Strik, Bernadine C., Connelly, Anne, Fisher, Glenn, and Granett, Jeffrey
Abstract:: Since phylloxera's discovery in a commercial vineyard in August of 1990, nine infestations have been verified in Oregon. With over 95% of Oregon's vineyards planted with ownrooted, Vitis vinifera, non-resistant vines, understanding the insect's biology under our conditions has become important for determining management strategies that minimize rate of spread....

Creator:: Sugar, David and Lombard, Porter
Abstract:: Four year old vines of 18 varieties were cane pruned, trained to a Scott Henry, thinned before veraison, and harvested in October and November 1993. Two of the varieties, Chardonnay and Cabernet Sauvignon, were used as standards. Only four varieties were spur pruned to reduce cropping or cluster size: Dolcetto,...

Creator:: Sugar, David and Hilton, Richard
Abstract:: The immediate objective of this project is to establish a vineyard at the Southern Oregon Experiment Station in which previously untested wine grape cultivars will be evaluated. The ultimate goal is to characterize the production and wine qualitypotential of these cultivars in southern Oregon.

Creator:: Sugar, David and Hilton, Richard
Abstract:: Climatic conditions in southern Oregon are unique among the wine-growing regions of the Pacific Northwest. Previous experience has shown that one strength of this region lies in the production of warm-climate cultivars which may not mature properly in other regions of Oregon. The current selection of such cultivars with known...

Creator:: Pinkerton, Jack and Candolfi-Vasconcelos, M. Carmo
Abstract:: Plant-pathogenic nematodes that cause yield loss in California and European vineyards are found in over 85% of Oregon vineyards. Population densities of Xiphinema americanum (dagger nematode) and Criconemella xenoplax (ring nematode) were found in 37% of vineyards at levels reported to cause 10-25% loss in California vineyards. However, these nematode...
